' Application filed June 8,

To (ZZZ "whom it may concern:

Be it known that we, ELI BROTHERS and JoHnT. LANCASTER, citizens of the United States, residing at Lynn and Beverly, in the county of Essex and State of Massachusetts, respectively, have invented certain Improvements in Upper-Pulling Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like partsin the several figures. I

This invention relates to shoemaking machines and particularly to upper pulling machines and is herein shown as embodied in a development of the machine shown and described in Patent'No. 1,029,387, granted Junell, 1912 on application of R. F. Mc

Feely. r

The McFeely machine-is organized topull an upperbypower-driven mechanism acting through yielding connections and then come to rest topermit manual adjustments of the upper. The yielding connections are set to give the tension which the operator judges that the upper stock will stand without tearing, tension adjusting wedges.

being provided for use in quickly resetting he updraw springsfor increasing or diminishing the tension which they shall apply according to the strengthof the stock that A limited extent-of additional manual pulling may also be and Sometimes is effected during this period ofrest.

To do that the operator reaches up and pushes upward on handles provided on the,

gripper carrying arms of the updraw levers.

The yielding connections expand to retain.

more or less of this additional pull It is characteristic of that machine that-1t pulls over the shoe by means of a yielding tension and holdsthe upper under tension by yielding mechanism until the upper-is fastened. From the time the grippers begin to pull the upper until they release it the updraw springs are acting to stretch the upper and are in condition to react to take up the stretch as the elastic upper responds to their pull. This'yielding pulling mechanism has two widely recognized advantages: It rendcrs a power-driven pulling-over machine self 'adapting within limits to r the wellknown difi'erences injelasticity of the upper stock of different-shoes, and it enables the pulling mechanismto apply to the upper as Specification of Letters Patent.-

when that tension is reached and will trans-j mit substantially that tension to the upper;

and as the upper gives the springs will expand to take up the stretch and will continue to apply approximately eighty pounds tension and no less as long as theyhold the upper. The organization of the machine shown in the patent is conducive to expeditious work and has given general satisfaction, althoughthe economy of its use is discounted to some extent in many factories by damage produced by tearing uppers which will not stand-the tension for which the machine is set when the shoe is subjected to the operation of the machine. Much of this damage could doubtless be avoided if operators possessed or exercised better judgment in recognizing upper stock that will tear, but a part of this danger of tearing it is'iinpractical for the-operator to recognize beiore the upper begins to stretch. In the quick-acting, power-driven. machine of that patent there is of course no opportunity for the operator to check the strain and prevent 'or stop the tearing after the pulling has bepulling the upper was substituted for the power-driven pulling-over mechanism of the McFeely machine. This machine has an 0bvious. handicap as to capacity and labor cost of the operation. In the machine of United StatesLetters PatentNo.1,169,%1i-,' granted on January25, 1916, upon the application of R. F. McFeely, a great advance was made by organizing the machine with a pull retardingmechanism that rendered the updraw slow enough to enable the operator to watch it, and by further equipping the ma; chine with a hand lever connected with both side grippers and arranged for the operator to seize during the slow upd1-aw.- By the use fof this lever'the operator can arrest the stretching oi": the upper produced through the updraw springs whenever 'he'sees that the tension which that particular upper can respective portions of the upper.

stand, or should receive, has been reached. The spring pull is retained in this machine; both sides of the shoe are pulled simultaneously so that the operator has to .watch both sides and cannot as readily detect the limit of elasticity at; either side asrif his attention were directed to one side alone; and

both sides are pulled to substantially the same extent because the pulling on both sides must be arrested as soon as the limit hasbeen reached on either side.

The presentinven-tion approaches the conditions :above outlined from a different standpoint and while retaining the advantages of power driving mechanism provides, as an important feature, novel means for pulling an upper at one or more points under such control, as to permit the precise llBIlSlQlYCjlGSlIGCl on any particular portion of thegiipper to be readily obtained without danger of overstraining the upper. The invention in its illustrative embodiment, provides power driven means for operating one gripper independently of others,- the machine shown having means for operating the grippers which engage the upper at opposite sides of the shoe independently of each other and under separate control for tensioni-ng differently, as desired, the different In the illustrated embodiment of the invention, moreover, :and in accordance with a further important feature, means is provided for imparting. a supplemental pull .to the upper subsequent to a prior pull which may be effected through readily yieldable connections with all the advantages attendant .ingly .or substantially unyieldingly, being 'upon a yielding pull. It is contemplated that the final'pu-ll may be effected unyieldpractically a dead; pull. In the construction-shown the unyielding pull is produced by the power driving mechanism under com- ,plete controlrof the operator, enabling him to check the pull instantly when he sees that the desired or permissible tensionhas been reached. A very importantcharacteristic of" this invention, as it is herein shown as embodied, is that when the pulling movement of the driving mechanism stops the stressing of the upper stops. There are preferably nousprings under tension in this mechanism to continue to apply pulling force. The great importance of this as at present advised is that the operator can stop the pull ,beforethe point of rupture of the stock is reached with confidence that there are no forces left at work which will cause tearing ofthe upper. It sometimes happens in the use of a spring pull that the rupture will begin to appear during the period of .the machines rest in consequence of. thecontinued. stressing by the updraw springs. If tearing begins while the stock is heldby a a spring pull it inevitably continues because 7 the force required to initiate the tearing is more than enough to extend a rent'which has been started.

Preferably and as herein shown a separate manual control lever is provided with a handle below the shoe for each side gripper and the final pulling of the two sides of the shoe may, if desired, be effected successively, preferably first on the inside, or the bigtoe side of the last, and then on the outside of the last. The control lever handles are, however, shown as arranged in such proximity that they can both be actuated simultaneously, :to the same or to clifferent extents, and by the one hand if desired. Important. safety devices also are provided, as well as means for locking the grippers against retraction from positions.

to which they are moved and automatic -.means for restoring the parts, including the j grippers, to normal relation at the end of their operation.

7 Another important feature of the preferred embodiment. of the invention is means for producing a stepby-step or intermittent'pulling, effected by rapidly-repeated short pulling impulses. Automatically acting lockingdevices are provided for holding each increment gained by the pulling impulses. These impulses are'shown as ob tamed by the use of ratchet faced friction clutch surfaces which are formed to slip past one another after applying a pulling tension determined by'the force with which the operator holds the. faces in contact by means of the control lever. The locking de- I vices, with or without the feature of intermittent pulling, hold the upper at the point to which itlias been pulled until the machine is restarted for the overdraw of the upper into. position-to be fastened and only after the-upper has been drawn inwardly over the edge vofthe shoe bottom under uuyielding tension sufliciently to bind the upper against :said edge are the locking devices released and the gripperspermitted to dea gripper or grippers at the will of the op- -erator in a direction to relax the pull upon the upper. shown, in which the opposite side grippers In the use of the construction may each'be moved independently in different directions as desired, the operator is thus enabled by powerto effect an adjustment ofthe upper to-position it in the correct relation to the last; and still another feature of the invention resides in power operated means for effecting relative adjust vention together with certain combinations of' parts and details of construction, all of which constitute features of this invention,

will now be described in connection with the accompanying drawing in which is illustrated the best embodiment of the invention now. known to us, but this machine has not the disclosure of the parts adjacent to it.

Fig. 3'is a perspective view of the control mechanism that is located on the left hand sideof the machine.

- A general understanding of the construction, organization and operation of the commercial type of pulling-over machine repre.

sented in said MeFeely Patent No. 1,029,387, will be assumed and this description will therefore be confined-to the new mechanisms and the parts closelyassociated'with them.

The base shaft or counter shaft 1 carries a large pinion 2 formed on -a constantly. running pulley. The pinion 2 drives continuously'two gears% and 4, Fig. 2, which are -mounted on short shafts carrying worms 5 and 6. The/worm 5 engages upon the outer or left hand side, viewing Fig. 2, ofa worm gear 7 and the worm 6 engages on the outer or right hand side of a worm gear 3. These gears are keyed 011 vertical shafts 9 and 10 which they drive in opposite directions as indicated by the arrows in Fig. 2. These shafts and their associated parts are alike for the right and left sides of the. machine and there is shown in detail in the drawings and will be here described only the parts which are located on that side of the machine which is on the right hand in Fig. 2, and isseen in Fig. 1. The v-erticalshaft 10 carries a worm 12 by -which it continuously drives a worm gear 14:

fast'on a horizontal shaft 16 that turns in bearings formed in a bracket secured'to the side of themachine head. The shaft 1.6 continuously drives a spool-shaped hub 18 which is splined on the shaft to move endwise and has on its opposite ends 20, 21 friction clutch members the. surfaces of: which are preferably irregular or, as shown, toothed. These clutch faces are adaptedto engage alternately with similarly formed. faces 22, on beveled gears 24, 25. [The formed as a screw 85.

surfaces of the clutch members are so formed that they hold until a substantial resistance is ei'iconntered and then slip to produce a series of'rapidlvrepeated, short shaip pulling impulses. The clutchhub 18 has a cir cumferential groove in which are received blocks on the forks of one arm of a hand I lever 28 which is fulcrumed in the bracket at '29 and extends downwardly and forwardly to the front of the machine below the shoe whereits end is inturned to constitute a handle 30. located where the operator,

standing in normal working position, can,

engage and manipulate it while he watches the shoe thatis being pulled. Raising the handle '30:forces the clutch hub 18 rear- -wardly along the shaft 16 and presses the gear. 24; Lowering the handle 28 forces the clutch hub 18 forwardly along the shaft 16 and presses-its friction face'21 into clutch ing engagement with the face 23 of the beveledgear 25.

42, Figs. 1- and 2, between which. is confined the end of a stud la'extendi-ng outwardly fromthe rear end of the usual .sidegripper lever -15. There may be a relief springbetween thestud 4 1 and the car 11, as shown in Fig. 1, to prevent breakage of the machine. This spring, however, is very stiff and does not relieve the unyielding pull which this mechanism is designed to transmit to the gripper and upper through the updraw lever 4C5. I

The updra wlever is. fulcrumed at 46 and carries the usual side gripper 4-7 depending from its front end. The rear end of the. lever .45 is connected through an adjustably tensioned spring 48 with the slide 49, 2, which carries a roll standing in a groove 52 in the front face of the brake cam 50, this being the characteristic construction for of footing the usual yielding updraw move-.. ment from the cam shaft of the McFeely machine. It is unnecessary particularly to illustrate or to describe. the well-known mechanism .of that machine cons sting of "the side grippers to engagethe upperat op- Cir posite sides of the last upheld with its sole face in a plane inclined to the vertical and against a. last bottom rest in position for an upper to be engaged by the side grippers and toe gripper and in position to permit the operator to have a substantially unobstructed view'o'fthe forward portion of theshoe during the pulling-over operation. Said machine also comprises automatic stopping mechanism to bring the machine to rest, after the upper has been yieldingly pulled, for the purpose of permitting inspection and adjustment of the upper, and mechanism is brought into action when the machine is restarted to seize and hold-the shoe while the'igrippers overdraw the' upper and give place to wipers and t'ackers which fasten the uppeinin pulled over condition.

. As stated, there is on the oppos'iteside of themachine from that shown in Fig. 1 mechanism corresponding to the new mechanism above described'as manually controllable by the operator for connecting the opposite side gripper to the power-driven operating mechanism, the handles 30 for the two controlling mechanisms being arranged in proximity as shown in Fig. 2. The machine operates as does the McFeely machine to seize and initially pull the upper yiel'dingly through the updrawlevers and the springs 48 by force transmitted from the cam 50, and

anothercam 54: for the toe gripper, on the The updraw cam shaft of the machine. springs may be light enough to producegrlpping and simply a preliminary pulling or straightening out of the upper, or they may be set to such a tension as to produce as much greater pull as may be desired. The new mechanisms controlled by the handles 30 will be operated while the machine stands otherwise at rest. These mechanisms may be employed for effecting adjustmentof the upper transversely about the last and for ad- 'ditionally pulling the upper to complete the stretching required for pulling "over the shoe. The completion on the stretching inay' be accomplished by movement of the two side grippers together or successively and to the same or to different extents. Prefer-ably they will vbe moved successively and also preferably the gripper on the inner side of the last will be raised first to updraw the upper on thatside, which is the more difiicult side of the last over which topull the upper because of the shape of thatside of the last, before the updraw is completed on the outerside of the last. The shape of the last allows the upper to be pulled readily' down from the cone of the last along the long, gradual slope toward the littletoo or outer side of the last, and the best fitting of'the shoe to the last is obtained under some conditions; depending somewhat on the shape of thelast, by drawing the upper into final position on the inner side-of side is being pulled.

' eration.

by the mechanism of this invention enables one side-of the shoe to be'ip'ulled and held by its side gripper in position while the other In this important respect-"the machineof this invention "differs from the Mc'F-e'elymachine in which the grippers are yielding at all times.

Provision is-made for locking the side grippers which have been yieldingly raised by the initial operation of the machine and also for locking them to hold all that is pulled by thesupplemental stretching effected by the use-of-the anechanism controlled by'the handles It will-be appreciated that when the shoe is presented to the machine the operator is liable to place the upper-farther in the jaws on one side of the shoe than 011 the other, and for that reason it is important to employ yielding means for initially pulling the upper in order that such means may adjust itself to compensate for the different extents to which the upper is put into thegripper jaws at the of the shoe after which the. springs for both grippers yield until the normal stroke of the: cam 50 is "completed. :This produces an approximately equal strength of initial pull at the two sides of the shoe, although it may be an unequal length of pulling a movement of the two side grippers, the handlesSO remaining undisturbed and the gears 24, 25 and 32 turning idle during this initial ophandles 30' the grippers can be caused to inove as desired, either together or sepa rately, for further t-ensioning the upper.

The locking means above referred to as its hub oppositely faced ratchet wheels 60 and'6l with whichcoiiperatepawls 62, 63 which are connected together by a spring Get, the spring tending toforce the pawls into engagement with the respective ratchet wheels. These pawls have heads between which 1s located an endwise movable cam -rod '65 which controls the engagement of the pawls with the ratchet wheels. The rodhas depressionsfifi, 67 cooperating respectively with the heads of the pawls 62,

with the. ratchets. The cam rod 65 is movable by interlocking engagement with the inner. fork, see Fig. 3, of the hand lever 28, which fork has forthis purpose an upward extension 68. The: cam rod 65has a pluengaged by a spring wedge pin '70 to hold it and the hand lever 28' in the position to which the operator moves them. WVhen the cam rod stands with itsfmiddle notch in engagement with the wedge pin 70, a portion of said rod of full diameter between the depressions 66 and 67 holds both of the pawls out of engagement with the ratchet wheels. This is the normal condition of the machine and prevails during the initial pulling operation. sides of the machine are returned to this centralv position and the pawls unlocked without attention from the operator after This is done by an arm 72 depending, from the handlever 28 into a fork of a lever 7st, Fig. 1. The lever 74L is'fulcrumed at '73 and is raised by a connection.

with the cross-head 75, Fig. 2, on the verticalrod .76 which carries the brake shoe .77 and. controls the starting and stopping mechanisnrof the machine, the connection comprising a link 75 which is pivoted to the lever and the crosshead. .This; rod. is

.raised by mechanism actuated by a foot treadle 7 8 when the machine is restarted to drive the fastening tacks, asv explained more fully i United States Letters Patent No. 791,986, granted on June 6, 1905, upon an application of R. F. McFeely, and the walls of the fork 74., by their engagement with the roll on. the arm 72 oflever 28,,return the lever and therebythe cam rod (35 to con tral position. In using the invention, after the upper has been initially pulled and the machine come to rest, the operator can throw in the locking pawls 63 for both side grippers' by slightly depressing the levers 28. The eamrods 6-5 are shown ashaving holding notches at either side of the central notch and by means of which the spring pins vwill hold the'cam rods in position moving gripper asffar as the operators judgment indicates that it "needs to be pulled. Theflever 28 assoclated with they other side gripper may then be similarly de-- pressed and the upper thereby posltively puller; at the OPPOSltG SHlG of the shoe. The

The rods for the twopawls will perform an important oflice in holding. from downward movement the gripper, which has been yieldingly uplifted for initially pulling the upper and prevents ing such displacement as would otherwise: occur whilethe gripper at the oppositeside of the machine is caused to pull theupper further. It isobvious thatqboth levers 28 1 i 7 justment of the upper longitudinally about the last is. efl'ectedby the usual tip straightening mechanism of the McFeely machine which is operated by the lever 292 shown in Fig. 1. Instead of depressing either hand lever 28 it may be lifted whereupon the clutch member 18 will be engaged with the gear 245. and rotate the screw 35 in the direction for lowering the gripper. Such lifting of the lever 28 adjusts the cam rod 65 for lifting the pawl 63 which prevents lowering of the gripper and throwing into operation the pawl 62zwhich prevents uplifting of the gripper. The new mechanism controlled by the levers, 28 can therefore we used to depress the grippers and relax the tension, which has been applied to the 7 upper, wheneverthat becomes necessary, This movement can be carried far enough tolow'er the grippers to initial position and cause them to release. the upper.

, As previously explainecL the teeth on the cotiperating clutch faces 20, 22 and 21, 23 are so formed that. a relative slip between the clutch members takes place when a predetermined resistance is encountered, wherelay-there is produced an intermittent pull consisting of rapidly-repeated, short sharp pulling impulses as distinguished from a steady pull such as would be produced by non-slipping or by smooth clutching surfaces. These intermittent pullingimpulses are peculiarly effective in stretching shoe uppers without tearing them;

To prevent accidents which might occur from movement of the levers 28 at inopportune times each cam rod 65 is extended rearwardly and "provided with a head 82 which cooperates with a rod80. The rods 80 depend from a cross-baron the cam slide 49,.see Fig. 2. The cam slide l9 positions the rods 80 during the upper pullingmovement and locates notches 81 in position to allow manipulation of the cam rods while the machine is at rest with the shoe under tension. At all other times the rods 80 prevent manipulation of cam rods and there- 'tor'e'ot'the hand levers 28 in a direction to cause the; grippers to pull the upper. 7 Toy avold danger of excess ve pulling by the new mechanism constituting the manually controllable connection between the power-drivenoperating mechanism and the beach of the pinions 24:, 25 is provided with a sliding rod or pin 90 which is adapted to engage an end face of the clutch member 18 and is so located with relation to a, wedge 92 as to be thrust endwise by thewedge when the pinion carrying it has been turned far enough to thrust the sleeve 36 to a certain limit of movement. This pin 90 and wedge 92constitute an automatic throw-out for always disengaging the clutch members when the limit of possible safe.

movement is approached and despite any pressure which the operator may unwisely apply to the hand levers'QS.

When the starting treadle 78 is depressed the machine starts at once as soon asthe brake islifted but on account of a slight lost motion and the fact that the clutch becomes eficctive before the brake rod arrives at its upper limit of movement thefork 7% does not effect release, through the described coni'lections, oi the gripper locking pawls until after the cam shaft has begun to turn and the tackers have moved, or begun to move, the'grippors inwardly for overdrawing the upper. Therefore the overdraw movement is made to occur, or to begin, with the grippers locked upunder hard tensiomand by reason ofthis fact and the inertia of the gripper levers and their 1 connections tending to render tardy any response to the strain of the upper when they are suddenly unlocked the overdraw is made tighter than heretofore.

The manner in which the invention may be used has been sniiiciently explained in connection with the foregoing description of the illustrated mechanism which constitutes the present preferred embodiment of the invention. It is obvious that there are features of the invention which may be used independently of others and that some features may be used in upper pulling-machines differingradically from. the illustrated machine.
